looks like they've already patched up the issue. Read on the THQ forum that people quitting are getting a loss now. The winner still doesn't get a win... but at least those jackasses disconecting are getting losses now. That's somewhat satisfying.
Still haven't tried a player match or the single player but played a level 50-something guy today and the win gave me 1100 points (lvl 22 now). I guess styles still make fights in the game because i whooped him pretty handidly, wore him down to the end of his health and finished him with a flying armbar (Me: Penn, Him: KenFlo).
